An arrhythmia is a problem with the speed or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is called bradycardia. Most arrhythmias are harmless, but some can be serious or even life threatening. When the heart rate is too slow, too fast, or irregular, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs.
University of Illinois at Chicago researchers have discovered a way turn pluripotent stem cells into atrial cells, which make up the upper chambers, or atria, of the heart. The discovery will enable them to better study atrial fibrillation, the most common heart rhythm disorder also known as AFib, which originates in the heart's atria.
With an increasing level of noise, the incidence of atrial fibrillation also increases dramatically. Scientists from the Department of Cardiology at the Mainz University Medical Center were able to prove this with data from the Gutenberg Health Study.
A medicinal plant frequently used in Traditional Chinese Medicine (TCM) - Evodia rutaecarpa - contains substances that can cause cardiac arrhythmia. This is what researchers from the Universities of Basel, Vienna and Utrecht have recently found out.
You've heard of "nature versus nurture," and philosophers argue about which is more important. But how does this work on the cellular level?
Heart disease is a major global health problem--myocardial infarction annually affects more than one million people in the U.S. alone, and there is still no effective treatment.
The Ohio State University Wexner Medical Center will establish the nation's first center dedicated to treating those with heart failure and arrhythmia with gifts totaling $18 million from Bob and Corrine Frick.
Researchers from the longevity biotech company GERO and Moscow Institute of Physics and Technology have shown that physical activity data acquired from wearables can be used to produce digital biomarkers of aging and frailty.
A study has shown that depression may be a risk factor for atrial fibrillation, a common heart rhythm disorder that can cause clot formation and stroke.
The heart is capable of terminating arrhythmias itself after local gene therapy, potentially avoiding the need for patients to undergo painful electric shocks, according to a proof-of-concept study presented today at EHRA 2018, a European Society of Cardiology congress.
Patients with atrial fibrillation could reduce the risk of dementia by taking stroke prevention medications, according to recommendations published online today in EP Europace, a European Society of Cardiology journal, and presented at EHRA 2018.
In the event of a cardiorespiratory arrest, two actions are crucial for the patient's survival: cardiopulmonary resuscitation and defibrillation.
Johnson & Johnson Medical Devices Companies announced today that Biosense Webster, Inc., a worldwide leader in the diagnosis and treatment of heart arrhythmias, enrolled and treated the first patient in its SHINE clinical study in Europe.
Johnson & Johnson Medical Devices Companies announced today that Biosense Webster, Inc., a worldwide leader in the diagnosis and treatment of heart arrhythmias, has completed patient enrollment in its U.S. Investigational Device Exemption study of the THERMOCOOL SMARTTOUCH SF Catheter.
To prevent cardiac death, people with certain cardiac disorders are implanted with electronic devices designed to automatically stimulate the heartbeat or counteract serious arrhythmia if necessary.
Wearing a lightweight vest equipped with a cardioverter defibrillator that detects abnormal heart rhythms in addition to taking recommended medications is associated with a reduction in the likelihood of dying during the first 90 days following a heart attack in people whose heart function was also impaired, according to a study presented at the American College of Cardiology's 67th Annual Scientific Session.
Researchers in the UPV/EHU's Signal and Communications Group in collaboration with researchers in the Oregon Health & Science University have developed an algorithm to guide an effective cardiopulmonary resuscitation maneuver.
Peter Ruben and his team of researchers have spent years studying why seemingly healthy patients with inherited cardiac arrhythmias can sometimes suddenly die during exercise.
Football players show structural changes in the heart and face an elevated risk of heart rhythm disorders later in life, according to research presented at the American College of Cardiology's 67th Annual Scientific Session.
Johns Hopkins researchers report successful use of heart imaging to predict the benefit or futility of catheter ablation, an increasingly popular way to treat atrial fibrillation, a common heart rhythm disorder.
Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia, and its prevalence is projected to rise continuously over the next few decades because of an aging population.
